What do you all think is the best ever movie based on a comic book, superhero or otherwise?

My personal favorite superhero flick is Batman Returns, but I believe that Tim Burton's first Batman film takes the cake as accuracy goes. Some other honorable mentions include the Superman series, the first Teenage Mutant Ninja Turtles flick, X-men (although it managed to screw up the continuity completley, i still loved it) and Spiderman. Some of the ones that sucked include Dick Tracy, the Phantom, Joel Schumacher's Batman flicks, and The Punisher.
